Your group is 30 people for a milestone birthday, and every listing you tap says up to 13 guests. So how many people can a charter yacht hold, really, and where is the boat that fits your whole crew? The honest answer from the helm: most Miami day charters cap around 12 to 13 guests, and that number is not the owner being stingy. It is how the US Coast Guard licenses a boat to carry people for hire. Cross that line and you move into a different, larger class of certified vessel. We run both kinds, so your headcount decides the boat, not the other way around.
How many people can a charter yacht hold?
Most private day charters in Miami hold about 12 to 13 guests, the practical cap for a boat licensed to carry passengers for hire. Larger certified vessels legally carry far more, from 26 up to 300 aboard our biggest event yachts. Crew are always counted separately from that number.
The exact ceiling for any single boat is printed on its Coast Guard paperwork, not guessed at the dock. For a typical 45 to 55 foot Miami cruiser or catamaran, that lands around 12 to 13. Step up to a boat built for events and the number climbs fast. So the real question is not a single magic figure, it is which tier of boat your group needs.
Why do most charter yachts cap at 12 to 13 guests?
Under US law an uninspected boat can carry no more than 6 paying passengers. Carrying 7 or more for hire means the boat must be Coast Guard inspected, run by a credentialed captain, and rated for a set maximum. For most day boats that certified number sits near 12 to 13.
The framework is simpler than the jargon makes it sound. Federal law defines an uninspected passenger vessel under 100 gross tons as one carrying not more than 6 passengers, including at least one paying passenger. That is the six passenger charter most people have heard about. Six paying heads is the wall for a recreational boat running trips without a formal inspection.
Go past six and the boat changes category. It becomes a small passenger vessel, and small passenger vessels are subject to Coast Guard inspection, which means a Certificate of Inspection, extra safety gear, and a captain holding the right credential. Push the headcount much higher and, depending on the size and tonnage of the boat, you move into an even larger inspected passenger vessel with more crew aboard. Each step up the ladder is a bigger, more heavily regulated boat, which is exactly why a random 50 foot yacht cannot just squeeze 40 friends aboard.
There is a comfort reason baked in too. Thirteen people on a 50 foot boat already fills the deck, the seating, and the single head below. The certified day boats we run are rated where the boat still feels like a good time, not a packed elevator. So the legal cap and the fun cap tend to land in the same place, right around a dozen guests.
Does the guest limit include the captain and crew?
No. The passenger number counts your guests only. The captain and professional crew are separate and never eat into your headcount. So a boat rated for 13 guests carries your full 13 plus the crew running it, and every person still gets a Coast Guard approved life jacket.
Every BillsIn charter comes with a licensed captain and crew, which past six passengers is the law and, honestly, just how a good day runs. If you want the detail on what the captain actually handles and why it is included, we cover exactly what comes with a captain on your charter. On safety, Florida and the Coast Guard require a wearable Coast Guard approved life jacket for every person aboard plus a throwable device, and that count covers you, your guests, and every crew member.
Our fleet, sized for every group from 6 to 300
Here is where it gets practical. Because we run 131 boats, your group size just points you at a tier. Small crew, big party, or a full corporate takeover, there is a hull rated for it, and the price is per boat, not per head. Everything below is a starting price for a four hour charter, plus tax and gratuity.
- Up to 12 to 13 guests: the core of our fleet of 131 boats, mostly 45 to 55 foot cruisers and catamarans, from around $990 for four hours. This is the tier for a birthday, a bachelorette, or a sandbar day.
- Up to 26 guests: the 120ft Baglietto, a superyacht from $5,500, for a crew that has outgrown a day boat but still wants real luxury and cabins.
- Up to 45 guests: the 80ft Sol event yacht from $4,000, a strong middle option for a bigger party or a company outing.
- Up to 120 guests: the 100ft Midsun from $5,000, built with multiple decks and a DJ booth for an actual event.
- Up to 130 guests: the 75ft Celeb from $3,500, our value pick when the guest list is long and the budget matters.
- Up to 300 guests: the 115ft Upus from $7,500, a floating venue for a wedding, gala, or corporate blowout.
What actually changes on a boat built for 100 guests or more?
The jump from a day boat to an event yacht is not just square footage. A vessel certified for 45, 120, or 300 people carries a bigger licensed crew, more heads, more lifesaving gear, and usually several decks so the crowd spreads out instead of bunching at one rail. It is inspected on a schedule, insured for the headcount, and run by a captain credentialed for that class of boat.
That is the machinery behind the number, and it is why an event boat costs more than a Sunday cruiser but carries ten times the people. You are not renting a bigger boat so much as booking a certified venue that happens to float. Once you understand that, the price tiers make sense: you pay for the class of vessel your headcount forces, and nothing extra.
What size charter yacht do you need for your group?
Match the boat to your headcount and the kind of day you want. A tight group under thirteen has the whole day fleet open to it, and the cost per person is lowest there. Once you are over thirteen, you are choosing an event boat, and the decision shifts to layout: how much deck, how many bars, and whether you need a real dance floor.
- 8 to 13 guests: a standard day boat. Best value per head, quick to book, ideal for a sandbar run or a sunset cruise.
- 14 to 45 guests: a smaller event yacht like the 80ft Sol. Room to move, space for catering, and it still feels intimate.
- 46 to 130 guests: a full event yacht such as the 100ft Midsun or 75ft Celeb, with multiple decks and a DJ setup.
- Up to 300 guests: the 115ft Upus, for a wedding or corporate event that needs a genuine floating venue.
